I have the stock muffler off a ZX9 I was thinking of maybe rigging it up and sticking it on my car, what do you guys think. It is stock and wasnt loud at all on the bike so on the car it probably stay the same.

:S  
car has much more exhaust output than a bike does.  
I’d think it would more back pressure than stock exaust.

Old timers used to run bike mufflers on old Datsun 240z’s… I don’t see why it wouldn’t work for you…

However 2.25 is a little choking… However the straight through design may be enough to satisfy your needs…

If you plan on going turbo… run 2 of them from a large collector…
